  2. abstract def init(view: BaseAccountStateView, consensusEpochNumber: Int): Unit
  3. abstract def process(msg: Message, view: BaseAccountStateView, gas: GasPool, blockContext: BlockContext): Array[Byte]

    Apply message to the given view.

    Apply message to the given view. Possible results:

    • applied as expected: return byte[]
    • message valid and (partially) executed, but operation "failed": throw ExecutionFailedException
    • message invalid and must not exist in a block: throw any other Exception
    msg

    message to apply to the state

    view

    state view

    gas

    available gas for the execution

    blockContext

    contextual information accessible during execution. It contains also the consensus epoch number

    returns

    return data on successful execution

    Exceptions thrown

    ExecutionFailedException revert-and-consume-all-gas, also mark the message as "failed"

    ExecutionRevertedException revert-and-keep-gas-left, also mark the message as "failed"

    RuntimeException any other exceptions are consideres as "invalid message"
